  • TIDA-00725: OTDR specifications

    Part Number: TIDA-00725 We are interested in TI’s developed OTDR solution TIDA-00725. We have gone through the document TIDUAZ1 but we have not been able to find the following basic and important OTDR parameters. Kindly let us know what values of…

  • RE: OPA2675: Laser Communication System

    Hello CSC, For specifically laser drivers/modulators, we have reference designs for very low frequencies intended to drive LEDs, and we have a very high frequency reference design for optical network communication which would be overkill for this application…

  • RE: Photodiode pulse detect system

    Resolved
    Hello Burak, 1) Are you saying you want to bypass the TIA? You would need a way to convert the current input source to a voltage which is best done by an amplifier configured in a transimpedance manner. Not sure about the detection speed for the MCU…
